v3.6.0

• Pregeneration Button Redesign: Fixed pregeneration button animation and styling. Restored original green colors for light mode and night mode with explicit overrides for maximum text readability and visual consistency.
• Prompt Optimization & Factual Warning: Updated the system prompt to enforce exactly 3 hints across all card types. If the front or back contains factual errors, the 3rd (last) hint is formatted with a warning symbol ⚠️ to indicate exactly what is wrong and explain the correct information.
